Our Company

Who are we?

We are a women-led, purpose driven luxury jewellery brand created in 2010 by Elaine & Emily, mother and daughter. We are determined to make inclusive and accessible ethical jewellery that is free from the corruption that still exists in the jewellery industry.  

There are three key principles that have always served as the pillars of our business: a passion for people, the planet, and quality. These principles guide and inspire every decision we make, shaping our purpose and driving us forward.

Firstly, we strive to create jewellery that brings boundless joy to our customers, whilst contributing positively to the lives of the individuals involved in its creation. The happiness of our customers is paramount to us, as we recognise the profound significance a piece of jewellery holds for the wearer. This includes our dedicated team, our cherished customers, and those within the broader community who benefit from our support and charitable initiatives.

Secondly, we recognise that the jewellery industry has hugely contributed to detrimental impact on the environment. That’s why we are also deeply committed to the planet and actively minimise our ecological footprint by using sustainable alternatives. Our decision to exclusively use lab grown diamonds and gemstones is one example of our commitment to preserving and protecting our precious Earth.

Lastly, we are unwavering in our pursuit of quality. We pour our heart and soul into creating jewellery pieces that are nothing short of exceptional. We believe that craftsmanship and attention to detail are paramount in creating pieces that not only stand the test of time but also hold deep sentimental value for our customers. We would never create anything that we wouldn’t be happy to wear ourselves!

What makes us ethical?

Ethica Diamonds is a purpose driven Cornish jewellery brand that specialises in diamonds and gemstones grown above ground and metals that are 100% recycled or responsibly mined. We are winners in the Jewellery Category for the Marie Claire Sustainability Awards 2023 and scored 100% in the Good Shopping Guide for ethical jewellers above big brands including Tiffany & Michael Kors. We support local communities, prohibit child labour, ensure safe working conditions, and we are a member of 1% for the Planet, pledging a portion of sales towards environmental preservation. We are also a member of the Living Wage Foundation.

In 2024, we have been very pro active and aim to give back even further to communities both far, wide and local. We have pledged to give a percentage of our profits to local charities doing good things including Cornwall Wildlife Trust, Cornwall Air Ambulance and Surfers Against Sewage. Another charity that is close to our hearts at Ethica is How Many Elephants, a non-profit organisation that is women-led, women-focused and impact-driven, supporting African elephants and female rangers on the frontline globally. We’ve also partnered with Greenspark to maximise our positive impact on the planet and its people. We are recording our C02 offsetting, plastic bottles that are rescued and tree and kelp planting.

We are a fine jewellery brand dedicated to harnessing the power of technology, working toward a future where there is no compromise between sustainability and beauty and make meaningful and ethical jewellery for our modern world.

Together, we aim to protect our environment and enhance lives and your support helps us make a difference.

Do your diamonds and gemstones come with a certificate?

Diamond certificates help authenticate a diamond’s characteristics for quality and pricing purposes. A certified diamond is very important to a consumer because without one it is much like buying a car without a warranty.

All of the stones we set are certified with the exception of small stones that are too small to be certified. All of our lab diamonds are certified by a mixture of bodies, including IGI, GCAL, and GIA and the Ethica Diamond is certified by both the IGI and GRI, using international standards.

Our Moissanite
Our Lab Grown Diamonds
Lab Grown Coloured Gemstones

Are all your rings ethical and sustainable or do only a selection of them match this description?

All of our rings and jewellery are set with the stones mentioned above. You can decide whether you want an Ethica Diamond or a pure lab grown diamond set within your jewellery.

We also use laboratory grown gemstones or natural gemstones from carefully sourced ethical suppliers, for customers who want to add some coloured gems to their jewellery.

All jewellery is individually made to order, so can be customised to your exact preferences.

Our Sustainably Rated diamonds are grown to the highest ethical and environmental standards and have a fully traceable, sustainably rated origin.  

What stone options do you offer?

We offer three options as an alternative to mined diamonds, all of which are lab grown and aligned with our company values of ethics and integrity. 

Lab Grown Diamonds
All of our lab grown diamond jewellery options are set with carefully chosen lab diamonds that are VVS clarity and a choice of D-F colour. 

Sustainably Rated Lab Grown Diamonds 
We have partnered with a small selection of diamond growers for this collection who are committed to climate neutrality and/or carbon negative efforts and investments in clean technology.  Our diamond growers use advanced technology which uses notably less energy than either industrial mining or standard lab grown diamonds that use fossil fuels for their production.  The energy they use is good energy — renewable hydro or solar power energy depending on the grower.

You can choose to upgrade to one of these diamonds on any of our jewellery if you prefer.

Ethica Diamonds
These are our signature gemstones which are very close in structure, composition and hardness to diamond offering the same toughness and longevity, and have the additional benefit of being considerably less expensive. They are independently certified, to international standards by the GRI or IGI.  Ethica Diamonds are a premium grade moissanite (silicon carbide) with a diamond infusion, cut and fully faceted to exact diamond proportions. Ethica Diamonds have incredible depth and realism, radiating the same sparkle and brilliance as the most expensive diamonds and are made to last forever.
We stock these stones at consistent E colour, VVS1 clarity and excellent cut so all Ethica Diamonds have these specifications. 

We can offer other colours in our signature moissanite such as champagne, blue, green and many others, and these are offered alongside our coloured gemstone offering. 

Coloured Gemstones
Our coloured gemstones are predominantly laboratory grown too, but sometimes customers ask us to source natural coloured stones to put into their jewellery. For these, we only use a supply that comes directly from the small scale mines where a special colour code system is in place. This means that we can select gems that have come directly which ensures they are ethically sound.

We have two different types of lab grown gemstones: those which are chemically identical to their natural counterparts with the same hardness (ie lab grown sapphires, emeralds and rubies) and coloured moissanite. We are excited to be the only company to offer coloured moissanite in a variety of beautiful colours. Moissanite is an especially hard gemstone (9.7 Mohs), meaning the durability is not too dissimilar to diamond. This is usually the biggest downfall when purchasing a gemstone, as they are generally much softer than diamond and are prone to scratches and chips.  Our coloured moissanite does not have this limitation.

Can you tell me about your supply chain?

We source lab grown diamonds directly from our growers, and the metals that we use are sourced by our manufacturers.

All of our jewellery is available set with lab grown diamonds and wherever possible, we select type 11A diamonds for their superior purity. We aim to select growers who utilise renewable energy or are working hard towards it and we are careful to exclude growers that do not show any commitment at all to clean energy.   

The only way to ensure lab diamonds are sustainable is to record the energy used to grow them, and offset this carbon, or ensure the energy used to grow the diamond is from renewable sources. Therefore, we also work with a small selection of diamond growers that are fully committed to climate neutrality for our Sustainably Rated diamonds.  These partners hold the following certifications SCS Global Services, SMETA, RMI, RJC, LBMA and Astute and are compliant with the United Nations Greenhouse Gas Protocol, scope 1 and scope 2.

Precious Metals 
We know that the mining of gold and platinum are not environmentally sound practices, using harsh chemicals, destroying ecosystems and risking workers lives where regulation is not enforced.

We are registered Fairtrade Gold jewellers and we give customers the option to choose Fairtrade Gold, if they wish. Certified Fairtrade Gold is regulated, and the workers are paid fairly. Fairtrade grain comes directly from the Fairtrade organisation and recycled grain comes from companies who recycle precious metals. 

Some of our designs are manufactured by a UK based company who have factories in the UK and India. They use 100% recycled gold and ethically sourced platinum. 

Our newest collection of jewellery designs are manufactured in India who are using fully recycled gold, which is SCS certified. They are highly committed to environmental good practice and their commitment to sustainability is exemplary,, which is why we support them as one of our suppliers.
For our bespoke pieces, our workshop uses 100% recycled precious metals since it operates at a much smaller scale.

You can find out more about the metals we use on our website here.

What is your commitment to Assay Assured UK Jewellery Hallmarking?

We are an Assay Assured Jewellery Retailer. Assay Assured status is only given to retailers who have been independently audited and verified by Assay Assured which is run and overseen by the Edinburgh Assay Office, and ensures that all precious metal jewellery (except items exempt by weight) are independently tested and hallmarked.

Each piece of Ethica Diamonds jewellery has been certified in accordance with the Hallmarking Act 1973, and will feature an official Assay Office hallmark.

Ethica Diamonds jewellery is beautifully crafted in a variety of precious metals such as 18K white, yellow and rose gold (standard or Fairtrade gold options)  as well as 950 platinum.

When it comes to manufacturing jewellery, precious metals (gold and platinum) are rarely used in their purest form. Instead, they are alloyed with other metals to enhance their strength, durability, and colour.

It is not possible to determine the precious metal content of an item by sight or by touch. It is, therefore, a legal requirement to have items consisting of gold and platinum independently tested and then hallmarked before they can be described as such. Items must bear a hallmark at point of sale, subject to the following weight exemptions:

Gold: mandatory for items above 1 gram; platinum: mandatory for items above 0.5 grams.

Ethica Diamonds is registered with the Birmingham Assay Office, ensuring our precious metal jewellery is compliant with the UK’s hallmarking regulations. All stock is subject to an internal confirmation process to ensure it meets the UK’s hallmarking regulations before it is dispatched to our customers.

Are there different types of laboratory grown diamonds?

Lab grown diamonds are made one of two ways – either through High-Pressure High-Temperature (HPHT), or through Chemical Vapour Deposition (CVD). CVD is the more highly valued method of growing diamonds.

High Pressure High Temperature or HPHT
HPHT recreates the natural growing environment found within the earth. There are a few different types of HPHT technologies used, but the process best suited for producing gem quality diamonds to be set in finished jewellery are created using a Bar press. The Bar press was invented by Russian scientists and uses a combination of inner and outer anvils to apply hydraulic pressure to the growth cell within the unit. The growth cell itself contains all the elements necessary to grow a diamond, including a tiny diamond seed, highly refined graphite and a catalyst consisting of a mixture of metals and powders. Consistent temperatures reaching 1,300 degrees Celsius and over 60,000 atmospheres of pressure are applied to the growth cell. Over a few days the elements within the growth cell melt and then reform during cooling to create a finished rough diamond ready to be extracted for cutting and polishing.
The entire HPHT growing process requires an incredibly controlled environment to produce a gem-quality diamond. Any shift or change during growth can cause the diamond to stop growing or can create inclusions that result in unusable diamonds. Every diamond must complete the entire growth cycle before the machine can be opened. It is only after the HPHT chamber is opened that we can see the finished rough diamond and its colour, clarity and size.

Chemical Vapour Deposition or CVD
Chemical Vapour Deposition, or CVD, is a process used to create gem-grade diamonds as well as optics and semiconductors. The process begins with a slice of a diamond containing the atomic blueprint for a new diamond to form. Carbon is added in a plasma reactor that reaches 10,000 degrees Fahrenheit, as hot as the sun’s surface. The CVD process uses ultra-pure carbon-rich gases in a controlled chamber. Carbon-based gases, such as methane, are heated until they break apart allowing the carbon atoms within the gas to separate. These tiny carbon atoms fall onto a diamond substrate and build up layers resulting in a rough diamond crystal. Atom by atom, the diamond lattice forms, the process by which diamonds form in nature is re-created. This process yields gem-grade Type IIA diamonds within 6 to 12 weeks resulting in a unique stone which is then cut, polished and graded by the same world-renowned labs that certify earth-mined diamonds.

While both offer a controlled environment, the HTHP is more costly and less energy efficient. The thermodynamic process involves placing a diamond seed into pure carbon, then exposing it to intense pressure and heat. The carbon attaches to the diamond seed in 14 different directions and forms a rough diamond with a complex cuboctahedron shape.

CVD is a more economical process, using vacuum chambers to convert carbon-heavy gases into plasma with less energy consumption. Kinetics allow the carbon atoms inside the chamber to build on top of the diamond seed in a single vertical direction, so the rough diamond grows into a cleaner square shape.

Ethica Diamonds favour suppliers that use the CVD growing method which has been the most successful in producing the highest quality diamonds with the highest purity.

How are lab diamonds more ethical if so much energy is required to grow them? 

It is not a given that lab grown diamonds are sustainable simply because they are grown in a lab and not mined. Many jewellery companies promote lab grown diamonds as “ethical” and "environmentally conscious” but this is not completely true and can be misleading to the consumer. 

Diamonds are grown in labs in countries including China, India, Singapore and the US, places that lean heavily upon fossil fuels for energy. The huge amount of power needed to create a diamond causes significant output in carbon pollution if the energy source is dirty, a point made in a 2019 Trucost report which found that, on average, greenhouse gas emissions are three times greater for lab grown diamonds than their mined counterparts. Greenhouse gas footprint per one carat of polished diamond is 160 kg CO2e per carat, which is 69% less than the estimated carbon footprint of lab grown diamond. 

The only way to ensure lab diamonds are sustainable is to record the energy used to grow them, and offset this carbon, or ensure the energy used to grow the diamond is from renewable sources. 

This is why we offer Sustainably Rated lab diamonds from a small selection of growing partners. They are fully committed to sustainability, taking time and care to grow the highest quality diamonds and not cutting corners to create cheap ones that are produced unethically that are now flooding the market.

Are lab grown diamonds real?

Yes! Natural diamonds and lab grown diamonds possess the same chemical composition and atomic structure, and therefore the same hardness and properties. Modern technology makes it possible to grow real diamonds in highly controlled facilities using state of the art technology. 

Under testing conditions, lab grown diamonds will be detected as real diamonds. Experienced gemmologists will be unable to tell the difference since they are indistinguishable by even the most expert eye.

What are the benefits of lab grown diamonds?

Lab grown diamonds are chemically, optically and physically identical to naturally occurring, earth-mined diamonds.

Lab grown diamonds are priced a lot more competitively and depending on the cut, clarity and colour, can be thousands of pounds less than a naturally mined diamond.

Conflict Free
The environmental consequences are minute compared to mined diamonds, and the industry free from humanitarian harm, unlike the diamond mining industry.

Does lab created or man made diamond mean fake?

There are many ways to tell the difference between a fake diamond and the real thing. Turns out, the definition of a real diamond is not linked to origin (earth vs lab), but rather by its characteristics and composition. Lab created or man made diamonds have been created replicating the earth’s natural process, and will pass a diamond tester because of their identical characteristics.

“They are real diamonds. They have the same optical, chemical, thermal, and physical features.”
Matthew Hall, Director, Gemological Institute of America (GIA).

What is an ethical diamond?

The true cost of creating a diamond falls under several headings, Environmental, Human and Ethical.

Where natural diamonds are mined, a huge hole is created in the Earth, and a small city is created on the surface to process the diamonds from the rock retrieved, and accommodate the workers.  This damages that piece of the Earth’s surface, probably forever.  The waste, the spoil, is stacked up somewhere and left to scar the area. The water courses locally are re-shaped, often poisoned from the runoff.  The trees and plants in the area are stripped away, and even if they’re replaced, the eco-systems will never be quite the same as the constitution of the soil will have changed.  The animals that lived there will have moved, or died.  The animals that used to migrate through the area will have been forced to use different routes to reach their destinations, putting extra strain on their bodies, causing weakness and ill health.

In first-world countries, mine workers are often highly skilled workers, well paid and well looked-after.  In poorer nations, where the industry is not so well regulated, diamond miners often work in treacherous conditions, where there is little concern for safety, and the pay is low.  In some cases, there is no pay, and women and children are also effectively enslaved by the mine owners, or where the diamonds are sold to fund conflict and rebellion.  The international diamond trade has tried to prevent these so-called ‘conflict diamonds’ from entering the market, by introducing the Kimberley Process, to verify diamonds’ ethical origins, but there are flaws and loopholes in this process, so you can never entirely guarantee that a mined diamond is free from human rights abuses.

At the very least, this means that the products we buy shouldn’t have a negative impact on the environment, animals or people who are linked to the creation of the product. But better still, looking for products and companies who go one step further by having a positive impact and support positive change is when it actually feels good to spend your money. That’s when products are truly ethical. After all, if you are going to spend money, you may as well choose companies who make you feel good about doing so and ensure your money is being used to support something good.

For a truly ethical purchase, you should choose a lab grown diamond that has been grown using clean energy or if they are not using 100% clean/renewable energy, say 50% is clean and 50% uses fossil fuel, you should choose a grower who offsets the carbon produced during the growth of that diamond using  carbon capture methods, so that it is at least carbon neutral. 

At Ethica, we select diamond growers who use renewable energy or offset carbon which makes them more sustainable than other lab diamonds on the market.  We are always looking for the latest innovations within the lab grown diamond and gemstone industry which match our company ethos and we’re proud to offer the most ethical options available.

What stone options do you offer?

At Ethica, we offer two ethical options to mined diamonds  that are ‘kind, not mined®’ –

The Ethica Diamond
Our signature gemstone which is a premium graded, lab grown moissanite that is infused with lab grown diamond. It is the only moissanite in the world to be independently certified to international standards by both the IGI and GRI, making it a very suitable option for an engagement ring in terms of its longevity and provenance. The Ethica Diamond is not tied to any fixed pricing structures, tainted with environmental or humanitarian harm and are even cheaper than lab diamonds, making them the most accessible alternative at a very attractive price point and are as close to diamond as possible.

Sustainably Rated Lab Diamonds You can choose which supplier you’d like your lab diamond to be sourced from and we can provide details of each supplier and their sustainability efforts, meaning you can make an informed decision which suits your wishes and budget. All of our jewellery is available with both options, the Ethica Diamond or pure lab grown diamond, as well as our selection of lab grown coloured gemstones.

I have seen a design that I like on your website, but can I make alterations to it?

We can make small alterations to an existing design to suit exactly what you want with our bespoke service, which is not only quicker but also more cost effective.

Allow 5 weeks to semi-customise any of our designs for you, for example, thinning the band, altering the claw/prong style, adding coloured gemstones or lab diamonds to the shoulders etc.

I understand that diamonds are an investment. Is that true for other options as well?

It is not entirely true that diamonds are an investment. The idea that diamonds appreciate in value is a a myth perpetuated by the marketing efforts of diamond cartels over a long period of time. Genuine rarity is a key factor when considering whether a diamond will hold or increase in value. This typically applies to very large flawless diamonds or rare coloured diamonds found in limited quantities.

The truth is with mined diamonds, you purchase at retail price and sell at wholesale price, and if you can sell it at all, you will only get a fraction of what you paid for it. Most diamonds are neither rare, nor valuable and are certainly no investment. People often confuse the worth with the cost and think because a natural (mined) diamond costs more, it is therefore worth more, but this is not true. There is little resale value in your average diamonds regardless of the origin.

The only way you will get your money back is if you claim on your insurance policy who will base the value of your loss against the diamond pricing index which is controlled by diamond producers.

However, the majority of diamonds, regardless of their origin, do not possess the characteristics of true rarity and value. It is important to understand that when purchasing a diamond, you are buying at retail price and should not expect to sell it at the same value. The only way you would ever get your money back is through an insurance claim for loss or theft if you have the original certification to verify the replacement "value".

What diamond size is right for me?

Bigger is not always better and stone size should be relative to personal style, stature, hand size, setting preference and budget.

Generally in the UK where style is more conservative, the 1 carat centre stone used to be the standard “desired” size, but now 1.5 and 2 carat are gaining demand. If you have smaller hands and a finger size L or lower, we recommend you consider a 1 to 1.5 carat. If you have larger hands with a larger ring size than L, you might want to consider a 2 carat. Anything over a 2 carat is more about personal preference.

Isn’t a diamond engagement ring an expensive luxury? Shouldn’t we be saving for the wedding?

Having a diamond engagement ring to show off your newly-engaged status to your friends is something that is ingrained in our culture, along with the unspoken tradition stating that an engagement ring should cost the equivalent of three months salary for the prospective bridegroom. When you consider that the pressure to spend that amount of money is purely social, yes, it does seem a bit ludicrous to be spending it on a piece of jewellery, instead of saving for your wedding (or house!).

Quite honestly, an engagement ring is a luxury. Indeed, many of our customers say that their pragmatic fiancées had suggested that a smaller ring might be sensible, given pressures on finances. However, choosing an Ethica engagement ring, set with either the Ethica Diamond or a lab grown diamond, brings the price down into much more reasonable territory, meaning that a lavish ring of their dreams doesn’t come with an extravagant price-tag, keeping everyone happy!

Choosing a man-made diamond is something that is an obvious choice for our customers, who already know about the dubious ethical practices of the natural mined diamond industry. If you need a little more information, please do investigate the rest of our website, where there is plenty of information about the environmental and humanitarian damage that is being done all over the world in the name of mining diamonds.

But isn’t a natural diamond more authentic and meaningful?

In an ideal world, anything that is natural feels better than something that is forced or manufactured artificially. But we don’t live in an ideal world and we need to balance the pros and cons. Natural doesn’t always mean better.

If we take a look at flower growing as an example. Flowers that grow naturally almost certainly will be damaged at some point by rain, wind and pests. Whereas flowers that are grown in polytunnels are protected from these harsh conditions. Both flowers are beautiful, but the protected ones will almost indefinitely be more consistent.

Similarly, stones that are formed in natural Earth conditions are also exposed to harsh conditions that result in a large percentage of wasted stones that are unsuitable for jewellery due to poor quality.

To produce one carat of diamonds, miners sift through about 250 tons of rock and sediment with the average diamond coming out of a mine being just one tenth of a carat, which is very small.  About 80% of approximately 142 million carats annually are used in industry for tools and cutting equipment etc. Only 20% are suitable for gems and of those, around just 2% are cut to the best standard.

Most of us would agree that all of this damage to our Earth is neither authentic or meaningful and if there is a kinder way, then it has to be better.

How does CZ compare to lab diamonds?

Lab created diamonds are 100% pure crystallised carbon, which makes them optically, chemically, and physically identical in every way to an earth-mined diamond.

Cubic Zirconia (CZ) is a well-known diamond simulant, normally set in fashion jewellery that has been used for many years to mimic diamonds.  CZ is made of synthetic zirconium dioxide in its crystalline form and is commonly used as a low-cost alternative to a mined diamond. It has absolutely no presence of carbon diamond bonds in its creation, it is simply a crystal cut in a way to mimic the appearance of a diamond. CZ is glassy in appearance and is very porous and becomes cloudy easily. The lack of crystallised carbon is why CZ differs chemically, physically, and optically from an earth mined and lab created diamond.

Lab Diamonds

What is a lab diamond? And are some more ethical than others?

A lab diamond is a diamond grown above ground. As the name suggests, lab grown diamonds are grown in a laboratory and a lot of energy is required  to mimic the conditions in the earth’s crust (intense high pressure and temperature) to form the crystallised form of carbon known as diamond. If this energy is supplied from burning fossil fuels, then those lab grown diamonds, although still more ethical than mined diamonds, cannot be called 100% ethical or sustainable.

However, there are a few select diamond growers in the world who have addressed this dilemma within this rapidly changing industry, and they do that by sourcing the energy required to grow diamonds from renewable sources. By using green energy to grow diamonds, their diamonds can be called truly ethical and sustainable, and we think that is pretty cool!

The Most Ethical Engagement Ring Choices 

What are type 11A diamonds?

Most people only think of just the 4’cs when judging the beauty of a diamond. However, there are also Types of diamonds. Type lA, llB and Type IIA, llB. In the past, we haven’t talked too much about the different types of diamonds because the superior Type ll has been unattainable to the majority of the population.

Type IA
98% of diamonds mined from the earth will be a Type lA diamond. These are very common diamonds that you will find at your local jewellers or online retailers.

Type IIA
Only 2% of diamonds mined will be a Type IIA diamond, making them very rare. They are special because they contain the purest form of carbon, with either very little or no nitrogen atoms in the crystal structure. This makes Type IIA diamonds harder and brighter than common Type lA diamonds. White diamonds are exceptionally colourless and coloured diamonds are often found with a brown, purple, blue, or pink tone.

Previously, Type IIA diamonds were only owned by royalty and the super-wealthy due to their incredible beauty and high calibre. For example, the Elizabeth Taylor Diamond and the Hope Diamond are both Type IIA Diamonds.

Ethica Diamonds only work with suppliers who grow superior Type 11A diamonds.

Type IIB
Type IIB diamonds, those defined as having trace amounts of substitutional boron, are prized for their blue colours. The famous Hope Diamond is a perfect example. Besides their boron content, these rare diamonds are also characterised by their general lack of nitrogen. Little is known about how type IIB diamonds form, but they are especially intriguing because boron is often regarded as a crustal element whose presence in mantle-derived diamonds is unexpected.


  • Type I diamonds are the most common. They represent 98% of all natural diamonds and have detectable traces of Nitrogen.
  • Type IA diamonds contain clusters of Nitrogen atoms throughout the crystal structure of the stone. They tend to emit a yellowish tone.
  • Type IB diamonds contain Nitrogen atoms as well. These atoms are all singular as opposed to clustered groups. These stones are 0.1% of all diamonds and emit a strong yellow, orange, brown and even green colour tone.
  • Type IIA diamonds are the most valuable and consequently are very collectable items. They contain either very little or no Nitrogen atoms in the crystal structure of the stones. White stones are exceptionally colourless and fancy coloured diamonds are often found with a brown, purple, or pink tone. They represent only 1% – 2% of all diamonds.
  • Type IIB diamonds contain elements of Boron within the structure. As a result, they often emit a blue or grey tone. They represent only 0.1% of diamonds. And consequently they are also very valuable.

Will lab grown diamonds test positive on a diamond tester?

Yes, these are real diamonds, which are pure crystallised carbon. Lab created diamonds will pass all tests used to confirm a pure carbon diamond.

Can you tell the difference between a lab grown diamond and a mined diamond?

Lab grown diamonds are identical to mined diamonds and it’s impossible to tell the difference between the two with the naked eye. Lab created diamonds are 100% pure crystallised carbon, which makes them optically, chemically, and physically identical in every way to an earth-mined diamond.

Are your lab grown diamonds inscribed?

Yes, each of our lab-grown diamonds is inscribed with its unique identification number. It is very small, and can only be seen with a jeweller’s loupe.

Can I see a video of the diamond before I purchase it?

There are 360 degree videos available for all our lab grown diamonds. They are photographed under 10x magnification and provide an excellent up-close view of the diamond before choosing to set it in a ring, or purchase it loose.

Please note, just like natural stones, lab grown stones also have variations in colour tones. This is due to the unique growth and cutting process of each stone. The videos shared may not always show the true colour, and it is normal to see slight variations in tone when ordering smaller stones. Please understand that due to the pleochroism (different colour shades when viewed from different angles) colour cannot be guaranteed. However, do not worry as different shades within the same colour category are normal and expected. 

The Ethica Diamond®

What is an Ethica Diamond?

Our signature gemstone, the Ethica Diamond, is not a lab grown diamond but a lab grown stone, which is precisely cut from premium grade silicon carbide (moissanite) with a diamond infusion and is independently certified by the IGI or GRI. Silicon carbide has a hardness rating of 9.7 Mohs, and with the diamond fused on the surface, the outer hardness is 10 Mohs (the scale of hardness and scratch resistance), which is the same as diamond. They are faceted and hand polished by trained diamond cutters in the same way diamonds are cut, which imitates the appearance of diamond very closely. Even jewellers may struggle to tell the difference.

The main questions that most people ask when considering an Ethica Diamond are:

  1. Will it stand the test of time?
  2. Is it made in an ethical way?
  3. Was it made using the highest standards of workmanship?
  4. Is it independently graded?
  5. Does it look and behave as the best diamonds do?
  6. Does it work with my budget?

Unlike other imitation products on the market that have no independent certification, each Ethica Diamond is individually graded and certified by either the IGI and GRI to international standards. The Round Brilliants carry the patented technology and are available with full IGI certification and all fancy shapes are certified by the GRI. Each stone over 0.35 carats is laser inscribed with its own serial identification number, just like natural and laboratory grown diamonds, and comes with a full, individual report which verifies the credentials and dimensions, for assurance and insurance purposes.

All Ethica Diamonds, GRI or IGI certified, are as standard:

E colour
VVS1 clarity
Excellent cut – (Hearts and Arrows in the case of round brilliants.*)

Our Stones 

*Hearts & Arrows cut is specific to the round brilliant shape stones and only around 2% of the world's mined natural diamonds are cut to this standard.

What are the benefits of choosing the Ethica Diamond?

Less Expensive
Ethica Diamond pricing is set fairly according to manufacturing and retail costs, making it significantly lower than the equivalent mined or lab-grown diamonds, and excellent value for money. 

This is especially noticeable on the larger carat weights. You can have a bigger, brighter stone for significantly less compared with the equivalent quality mined or laboratory grown diamond which can retail for thousands more.

Ethica Diamonds are just as sparkly and brilliant as the most desirable natural or laboratory grown diamonds and are made to last forever, to be passed on through the generations – just like diamond.

The presence of internal birthmarks (known as inclusions) can make lower grade natural and lab diamonds more susceptible to breaking. Referenced as the clarity of the diamond, the more inclusions, the weaker the structure of the diamond. Ethica Diamonds are IF-VVS1 clarity, which is the highest grade. This means they are less susceptible to breaking compared to an average clarity diamond.

We use the best credentials to create the Ethica Diamond. Colour (E) Clarity (IF-VVS1) Cut (excellent/ Hearts & Arrows).

All Ethica Diamonds are independently certified by either the IGI or GIA using international benchmark grading standards and every stone is laser inscribed. This is the same process as laboratory grown and natural diamonds and is done for identification purposes.

No hazardous chemicals or other environmentally dangerous substances or processes results from the creation of these beautiful gemstones, making it a truly meaningful symbol of your commitment.

But if this isn’t for you, we also specialise in laboratory grown diamonds, which are pure diamonds. 

Will my Ethica Diamond last a lifetime?

The Ethica Diamond consists of a core of super white silicon carbide, which is then infused with lab grown diamond, resulting in an overall hardness of 9.7 and surface hardness of 10 on the scratch resistance scale (Mohs). The overall and surface hardness of diamond registers at the highest which is 10.
Silicon carbide has an incredibly tough crystal structure and conveys many qualities that are comparable to diamond, particularly its hardness and durability.  The crystalline structure of silicon carbide is very similar to the tetrahedral arrangement of carbon atoms in diamond, which means it behaves in a very similar way and will last a lifetime, just like diamond.

Treat your Ethica Diamond as you would a natural diamond and it will last many generations.  Just like any other diamond jewellery, a gentle cleaning is all it needs to maintain its dazzling sparkle. We also offer a lifetime warranty on every Ethica Diamond, for extra peace of mind.

Can anyone tell the difference between an Ethica Diamond and a diamond?

When it comes to diamonds, your expectations are high. You envision a stone that exudes clarity, refracts light with unparalleled brilliance, and boasts a hardness that culminates in crisp, precisely cut edges. That’s what makes the Ethica Diamond so extraordinary; to the naked eye, most people wouldn’t be able to tell the difference between the Ethica Diamond and a natural diamond. They possess the same clear colouring, the mesmerising sparkle, and the unmistakable hardness - the captivating traits which define a diamond.

Just like their natural counterparts, these gemstones undergo independent certification according to international standards by renowned institutions such as the GRI or IGI and each Ethica Diamond comes with a comprehensive grading report, providing you with complete transparency and confidence in your jewellery. 

We don’t want our jewellery to be mistaken for diamonds though, so an identity number is laser-etched onto the girdle of every single stone, so that they can be distinguished.  Don’t worry, this can’t be seen by the naked eye and all certified natural diamonds and laboratory grown diamonds have them, too.

Will The Ethica Diamond scratch glass?

The ‘quick and dirty’ test of a diamond is ‘will it scratch glass?’ Simulated diamonds, such as cubic zirconium, are not as hard as real diamonds, and will not leave a mark on glass. Ethica Diamonds will.

Hardness is measured on the Mohs scale of scratch resistance, where diamonds score the maximum, 10. Glass scores around 6.5, and Ethica Diamonds are at 9.5-9.7, meaning they can scratch glass.

What's the difference between hardness and toughness?

The Mohs scale was created to be a reference for the 10 most common minerals ranked in order of increasing hardness. At the top of the scale is diamond (10) and directly below it is Corundum (9), which is what rubies & sapphires are made from. At between 9.5 and 9.7, the Ethica Diamond is just above Corundum but below a diamond.

Hardness with reference to gemstones is often misunderstood. The word “hardness” has a very specific scientific meaning in gemmology that differs considerably from its everyday usage. The scientific definition of hardness is the ability to resist scratching, nothing more.

Hardness depends on the bonds that hold the atoms together within a crystal structure. This bonding is reflected in the ease with which the layers of atoms at a surface can be separated by applying pressure with a sample of another material. If the second material is harder than the first, it’ll leave a furrow, or scratch. That represents the breaking of millions of atomic bonds on a microscopic scale. The hardness of a mineral is, specifically, the susceptibility to scratch. Every mineral can be ranked based on other minerals it can scratch.

The Mohs Hardness scale ranges from 1-10 in measuring the hardness of a gem (Resistance to scratching).  It was created by the German Gemmologist, Freidrich Moh. Ten is considered the hardest point.

Is the resistance to chipping and breaking.  Natural diamonds have internal birthmarks (inclusions) and are graded from best quality to least. (FL-VVS1-VVS2-VS1-VS2-SI1-SI2) and so the lesser quality diamonds have a weaker internal lattice structure, which can cause them to crack or chip under pressure or a knock.

Because Ethica Diamonds have a very high clarity of VVS1, they are not susceptible to breaking or chipping and may be tougher than the average quality natural diamonds, since the majority of natural diamonds do not surpass the clarity of VVS1.

Can I damage my Ethica Diamond?

Every gemstone, including diamond, has the potential to chip, particularly on the corners or edges where the structure is thinnest, since this is how gemstones are cut to specific proportions in the first place. The Ethica Diamond, although extremely durable, is no different, so although it can easily handle everyday activities and is very unlikely to ever be damaged, it cannot be guaranteed.

Read about how to care for your Ethica jewellery here.

Carat weight and the Ethica Diamond

The carat (ct) of a stone reflects dimension more than weight itself: it is the size that accurately dictates the ‘carat’ of a gemstone. This is because different gems have different weights but must adhere to size in order to be utilised for the manufacturing of jewellery. Our created gemstones are fractionally less dense than diamonds of the same physical size.  So the 1 carat Ethica Diamond is 0.93ct in weight compared to diamond, but is always 6.5mm in diameter, the size of a pure 1ct diamond. The Ethica Diamond is always the same size in mm as a diamond of the same carat weight. No refunds or adjustments will be made relating to the carat weight of the stone that you have purchased.

Is the Ethica Diamond different from standard moissanite? 

The Ethica Diamond is produced using patented technology, where CVD diamond is grown at an atomic level to the surface area of the silicone carbide (moissanite). A super premium grade moissanite is cut and polished to exact diamond proportions prior to the diamond infusion treatment. This treatment adds benefits to a standard moissanite gemstone which include:

  • Enhances the surface hardness to 10 on the Mohs scale of scratch resistance, which is the same as diamond. This increases durability. 
  • Enhances the overall look of standard moissanite, giving it a more adamantine lustre, more comparable to diamond. 
  • This is the only moissanite to be graded by the IGI, which is reflective of the quality of the stone. The IGI is a world renowned independent grading institute for diamonds (both natural and lab grown).

Please note that the option to upgrade to an IGI certificate is currently only available for the round brilliant Ethica Diamonds.

Is the Ethica Diamond guaranteed?

  • We offer a lifetime guarantee on every Ethica Diamond against manufacturing defects.  
  • Ethica Diamonds over 0.35ct are laser etched with a unique serial number for individual certification, the same way that naturally mined diamond and laboratory grown diamonds are certified.
  • Every Ethica Diamond over 0.35ct comes with full grading certification from the IGI or GRI, which identifies the stone credentials. The stone is fully traceable online, via the GRI or IGI website.
  • We give you a 14 day home approval promise on every purchase.  We are confident that once you have seen, touched and worn the jewellery you have purchased from us, you will be delighted with it. Therefore, we will take it back if you are not happy with it, provided it remains in new condition and returned with all the original packaging. Please refer to our Return or Exchanges Policy for details.
  • Should your Ethica Diamond be lost, stolen or damaged, and you need to claim under your own insurance, we are happy to provide any additional paperwork that your insurers require, to prove the value or type of stone, and any ongoing help you require through this process.

For full information, please refer to our Lifetime Manufacturing Warranty.

I’ve heard about the 4Cs of diamonds. How does the Ethica Diamond compare?

The 4Cs of diamonds are traditionally Cut, Clarity, Colour and Carat.  In recent times, Conflict has been added as a fifth C, and we also believe a sixth C, Cost, is important.

All round brilliant Ethica Diamonds are created with the ‘ideal’ ‘hearts and arrows’ cut which is the perfect cut for maximum sparkle and symmetry. Less than 2% of mined diamonds achieve this cut, as they have to be cut according to internal faults in the stone. All other shapes in the Ethica Diamond range are cut to ideal/excellent standards. They are hand-cut and polished by experienced, fastidious diamond polishers.

This describes the tiny imperfections found within a diamond. The number and size of these inclusions determine the grade of clarity they are given. The Ethica Diamond has clarity graded between Flawless (FL) and VVS1, – ‘very very small inclusions’. A diamond can be described as “flawless” only if it has no visible imperfections when viewed under 10x magnification by a skilled diamond grader.

The less colour there is in a diamond, the more valuable it is.  Colour is graded alphabetically from D to Z, with D being perfectly colourless.  All Ethica Diamonds are graded E which is superior quality to many diamonds used in jewellery.

A diamond is measured in carats, which describes its weight, rather than its size. This does mean that stones of similar carat weights could look very different.  As laboratory grown diamonds (CVD/HPHT) are of very similar density to mined diamonds, the carat weights are more or less the same. We measure our stones in millimetres, and a 6.5mm round Ethica Diamond is equivalent to a 1 carat diamond of the same cut, although it weighs 0.93 carats.

The Ethica Diamond has no links with conflict, or humanitarian abuses, unlike mined diamonds.  Even natural diamonds marketed as ‘conflict free’ are not 100% guaranteed to come from conflict-free mines, or be un-tainted by other human-rights issues.

Most of us are now aware that the supply of diamonds is controlled to keep the cost of them artificially high and the pricing is set by diamond producers.

Ethica Diamonds are fairly priced and not tied to a pricing index.

Sustainably Rated Diamonds®

What is a Sustainably Rated Diamond®? 

Sustainability is our passion and we are taking dedicated steps to show complete transparency in our supply chain, which is why we have carefully chosen a handful of  licensed diamond growers around the world who are dedicated to sustainability and adhere to  strict ESG (Environmental, Social and Governance) practices. 

These growers take  time and care to grow the highest quality diamonds  that are visually, physically, and chemically identical to earth-mined diamonds; the difference is that they are grown above ground and have a fully traceable, sustainably rated origin. No other standard provides this level of assurance to customers.

They use a variety of energy sources during the growth production of their diamonds, applying various technologies to measure energy consumption. Even if 100% renewable energy is used, there are still minor differences that are then offset. Accurate numbers are used to calculate the amount of carbon offsets that are required to remove any carbon impact. 

This ensures the highest ethical and environmental standards that are based on climate neutrality efforts and investments in clean technology.  

Are natural diamonds sustainable? 

One of the major challenges the traditional diamond mining industry faces is its reliance on fossil fuels. De Beers produced 34.6 million carats of diamonds between 2022 and 2023, using over 455 million tons of displaced earth, 1.3 billion litres of fossil fuel, and 372 billion litres of water in their production. Other challenges include destabilising ecosystems, pollution & poisoning water supplies & massive health risks for local communities.

To produce just 1 carat of earth mined diamonds, approximately 100 square feet of land is disturbed and one out of 1,000 workers are injured. 

Are lab diamonds sustainable? 

At Ethica, we only use lab grown diamonds, bypassing the whole conflict free conversation entirely. However, what lab diamonds do not bypass by default is the fully sustainability conversation; It is not a given that lab grown diamonds are sustainable simply because they are grown in a lab and not mined. The only way to ensure lab diamonds are sustainable is to record the energy used to grow them, and offset this carbon dioxide, or ensure the energy used to grow the diamond is from renewable sources which is exactly what we do at Ethica. 

How do I know what type of energy is being used to grow my Sustainably Rated Diamond®? 

Our Sustainably Rated Diamond® partners adopt various methods to ensure their diamonds are produced in a carbon neutral way. You can choose to upgrade to a Sustainably Rated Diamond® with any of our jewellery and, depending on the grade that you choose, we will carefully handpick your diamond from our inventory.

All of these diamonds are provided with individual, third-party certificates issued by SCS Global Services, Inc and/or SMETA, and are created through sustainable production practices.  Each certificate provides assurances that rigorous environmental, social and governance compliance standards have been met and all of these diamonds are fully traceable and certified for Climate Neutrality. The methods used to grow these diamonds include solar and hydro. Other GreenHouse Gas (GHG) emissions are offset in accordance with the United Nations Greenhouse Gas Protocol, scope 1 and 2 and only the minor difference of operations are offset.

Can I choose the grower for my Sustainably Rated Diamond®?

If you have a preference on the energy used to grow your diamond, just let us know and we will select your Sustainably Rated Diamond® only from the inventory according to your request. Please note that there may be a delay for the stone shape and stone size to become available that you have chosen, particularly if you have selected a size or shape that is not held in stock. 

What about the transportation if manufacturing is outside the UK?

Our goal is to meticulously monitor energy consumption throughout the entire supply chain, spanning from the manufacturing stage to the point of sale and ultimately to the jewellery's final destination. This comprehensive approach ensures that our supply chain operates as close to carbon neutrality as possible, encompassing manufacturing and product transportation.

Moreover, we actively seek partnerships with shipping and logistics companies that operate on renewable energy and share our commitment to preserving the environment by offsetting their carbon footprint. 

Do I pay more for a Sustainably Rated Diamond®?

Sustainably Rated Diamonds® command a premium over regular lab grown diamonds due to their adherence to elevated standards. We meticulously trace their origin, manufacturing processes, energy sources, factory trade practices, and various other factors. By enforcing stringent standards upon our partners, the operational expenses increase, necessitating a higher price point to ensure the accuracy and integrity of our offerings. The costs associated with the offset measures taken are factored into the diamond's pricing structure.

How do I know if the workforce are treated fairly and if the factory is safe where my Sustainably Rated Diamond® is grown?

In addition to our commitment to sustainability and traceability, transparency is a core principle of our operations. Our rigorous vetting process, guided by the stringent criteria of the ESG practices, guarantees that all our diamond growing partners are dedicated to Fair Trade practices who regularly conduct thorough audits to ensure their ongoing adherence to these standards.

What’s the problem with fossil fuels anyway?

Fossil Fuels have been relied upon to give us everything we use from lights down to clothes we wear and the houses we live in. The issue is that there is so much carbon dioxide in the atmosphere right now, every living thing (including the air and oceans) is not able to adapt fast enough and it is slowly suffocating life on our planet. The goal is to bring the current 420 PPM of carbon dioxide in the atmosphere down to 350 PPM. You can find an accurate measure of atmospheric carbon on NASA's website here.

What is carbon offsetting? 

Companies that are aiming to use 100% renewable energy, is a positive step towards sustainability and it is ultimately the way forward. However, the world will not be able to achieve this quickly enough and being “carbon neutral” will not be enough on its own to avoid climate disaster.

Carbon offsetting provides an answer to the day-to-day emissions created that can’t be prevented. This  process is how our growing partners compensate for their emissions by funding projects that provide sustainable development in communities around the world. These projects offer an equivalent reduction in emissions to those created; either counteracting or absorbing carbon dioxide and helping to restore balance to the environment.
It’s a strategy that’s already been adopted by many big brands from around the world, including the likes of EasyJet, Shell, and Gucci, who all now use Carbon Offsetting to help improve the environmental impact of their businesses. 

As a result of unethical or questionable tactics with carbon offsetting, many companies, including Shell Oil are steering clear of it. However, there are legitimate and essential ways to offset and it is important to understand that there is no single silver bullet that will address climate disaster.

Why do we need to remove carbon dioxide from the atmosphere?

To meet global commitments and avoid the worst impacts of climate change, it’s imperative we reduce the carbon emissions we add to the atmosphere each day. But, the science now shows that emissions reductions alone will not be enough to limit global warming to 1.5°C. We must also remove billions of tons of excess carbon dioxide (CO2) from the atmosphere.
In the short term, carbon removal can help bring global emissions down to net zero, by providing a tool to address difficult-to-decarbonise sectors, such as aviation. In the future, once deep emissions cuts have been made, carbon removal may be needed to bring the overall level of CO2 in our atmosphere back down to levels deemed safe by scientists.

We all have a part to play in achieving a low-carbon future and for homeowners, this means being given the chance to balance their carbon footprint. For the environmentally conscious and those looking to reduce their impact on the climate, carbon offsetting gives them the tools to make a difference. Whilst it shouldn’t be used as a stand-alone approach and is best used as part of a wider carbon reduction strategy, it will help people reduce their impact on the environment.
To learn more about the different types of carbon removal and why it’s a necessary part of climate mitigation, check out this video explainer by World Resources Institute.

How can carbon emissions that we can't control be offset? 

The beneficiaries of carbon offsetting could be anything from helping some of the poorest households in West Africa to access eco-friendly cooking equipment, to supplying clean hydroelectric power to the local grid in rural China, the options are diverse. One example is the Kariba REDD+ Forest Protection project in Zimbabwe, Africa. Since its launch in 2011, it’s avoided more than 18 million tonnes of carbon dioxide from being released into the atmosphere and has prevented deforestation in an area of nearly 750,000 hectares.
While carbon offsetting might not be the only answer, it’s part of a much bigger solution. It’s true that many of us are already doing our bit in all areas of life to reduce our carbon footprint but choosing great initiatives such as carbon offsetting is yet another step in the right direction. By supporting worthy sustainability projects that deliver quantifiable greenhouse gas reductions, we can all play our part in securing the future of the planet.

In the UK, the net-zero strategy released by the government last year includes at least 5m tonnes of CO2 (MtCO2) per year of “engineered” removals by 2030, scaling up rapidly to 23MtCO2 by 2035 and 75-81MtCO2 by 2050.
As it stands, these engineered removals – technical solutions such as bioenergy with carbon capture and storage (BECCS) and direct air carbon capture and storage (DACCS) – are essentially non-existent in the UK.

Our selected diamond growth partners support high-impact projects, from supporting Artisanal Scale Mining communities around the world, to funding ICIMOD's Himalayan Climate and Clean Air Project, an ambitious effort to dramatically reduce black carbon and other emissions in this critical ecosystem.

Is offsetting a form of greenwashing?

Greenwashing is an exaggeration of a company's environmental credentials. This is completely different from offsetting. Offsetting removes carbon dioxide out of the atmosphere that is used during production of the product. Greenwashing is given to companies that claim they are helping the climate more than they truly are.
However, there are methods of offsetting that are also greenwashing as Forbes investigated.

How do I care for my Ethica jewellery?

What we love, we look after. Taking care of precious metals, diamonds and gemstones is actually really easy. With a little tender loving care, you can go a long way to keeping your jewellery in excellent, sparkling condition.

  1.  Be sure to remove your jewellery when doing activities or duties which would strike, repeatedly wear, knock or potentially cause damage.
  2.  Never put multiple earth mined and/or man-made precious stones and gems together as this could scratch your stone.
  3.  Keep lotions, perfumes, oils, cake soap, and skin oil away from your jewellery. Please keep your stone clean as this will ensure maximum fire and brilliance.
  4.  The best way to clean your Ethica Diamond jewellery at home is to use warm water, mild dishwashing liquid and a (very soft) toothbrush. For professional cleaning, see your local jeweller for ultrasonic cleaning.

Diamond is the hardest mineral we know of, but they are not indestructible. They can be scratched, chipped or split by sharp edges. No one wants that, so take care when wearing and storing your diamond jewellery. We always recommend you keep your Ethica Diamond jewellery in its box or case. Also always be aware of diamonds scratching diamonds, so lay your diamonds out flat wherever possible.

The lustre and patina of gold is gorgeous. It does not tarnish or fade over time. In its pure form however it is very soft and care should always be taken not to scratch or knock it against hard surfaces.

We recommend that you wear rings of a similar Karat together, e.g. your wedding and engagement ring, as the higher the karat of gold you wear, the softer the metal and one may wear down the other over time.

Gold should be cleaned regularly in order to maintain its beauty. A soft, lint free cloth is a very effective way to keep gold jewellery looking beautiful. Gold does not like chlorine or bleach so be aware of this when in a swimming pool or hot tub.

Platinum develops a natural patina that many people prefer over the “just polished” look.  When this happens, you can send it to us or take it to your local jeweller to have it re-polished back to its new high-shine look.

As with diamonds and gemstones, you should take care to protect any precious metal jewellery by keeping it safe in the jewellery box it came with or a chamois bag.

We have a care booklet with every piece of jewellery purchased that explains our recommendations for how to care for your jewellery.

You can also download our care guide here:

Jewellery Care Guide

Do you offer insurance for the delivery or beyond delivery?

All of our jewellery will arrive discreetly packaged, double boxed for protection and security and is fully tracked and insured via Royal Mail Special Delivery.

Once received, our jewellery can be insured easily but we don’t recommend any particular insurer. Usually people insure their items of jewellery from us under their existing insurance.  Most insurers will offer insurance on itemised valuables over a specified amount, and this can be added onto your standard house insurance.

Do you offer ring engraving?

Yes, we offer engraving on the vast majority of our engagement rings and wedding bands, which you can choose from the product page when you are shopping. The cost is £95 and we recommend no more than 15 characters for engraving on standard sized rings. Please get in touch to request this service if you can't see it listed on the product that you wish to purchase. 

If you wish to add engraving at a later date, we can easily arrange this for you.

Please note that engraved rings are excluded from our returns policy and therefore cannot be returned or exchanged.

Orders & Shipping

When will my order arrive?

All Ethica, jewellery is made to the highest level of quality, and handcrafted especially for every customer.

Standard Delivery – approximately 5 weeks
Priority Service (additional £110) – reduces the lead time by approximately 10 working days
In Stock items – approximately 1 week

  • During quieter periods, we can deliver much earlier than these given times, so please contact us or call us (+44) 01872 222248 if you have an urgent request.
  • There are situations that may fall outside our control during the manufacturing and setting process. This means that we will do our very best to deliver when we have estimated, but we cannot 100% guarantee the estimated delivery date whether your order is placed on standard delivery or priority service.
  • Shoulder set rings - jewellery set with small stones - and selecting the fairtrade gold option will require a few extra days. Every stone is set by hand in the UK, and setting more stones takes a little longer – we want to get it perfect for you.
  • Bespoke orders take from 8 weeks, as we need to work closely with you before the design of your piece of jewellery is signed off and you are happy, before we start to create it. The complexity of your chosen design will usually dictate how long this process will take – and can take longer, but we won’t start creating it until you are 100% happy to proceed and at a pace that you are completely comfortable with.
  • We will advise you of the estimated delivery date by email once we have received your order, but the exact date of delivery is not known until it is confirmed with our manufacturer and our workshop.
  • Delivery dates will depend on the time of year and we are very busy from Black Friday, through till the run up to Christmas. Lead times will vary and from the beginning of December, we may not be able to offer the priority service. Orders made over the Black Friday period cannot be guaranteed for pre-Christmas delivery.
  • No refunds will be given on the priority service fee unless the delivery date exceeds the standard delivery estimated date applicable at that time.

How do I know what size ring to order?

We have a lot of information about getting the sizing right for your ring on our website.  There are various ways of measuring: using an existing ring, visiting a local jeweller, or using our printable ring-sizer. 

For more information please view:

Finger Size Guide. 

How do I place an order?

After choosing an item you would like to purchase, follow the instructions and proceed to checkout. If for any reason you are unable to order in this way, please contact us with the details of your purchase, together with your name and telephone number. We will then contact you to arrange payment and delivery.

We have a live chat option, where you can talk directly with one of the Ethica Diamonds team, as you progress through the ordering process.  If no one is there at the time you request a chat, please leave your name and contact details and we will be in touch the following working day.

Alternatively, you can contact us by sending us an email or call us on (+44) 01872 222248.

  • You can pay by phone, using a credit or debit card.
  • You can set up interest free credit to pay in instalments, via our website.
  • You can pay by PayPal or cheque.
  • You can pay by BACS transfer, from an invoice. This is a preferred option by us for bespoke orders that can take between 8-13 weeks to process.

Is VAT charged online?

All prices displayed on our website are inclusive of UK VAT. For all orders outside of the UK, VAT is not applicable.
We can process your order manually via our invoicing system which is net of VAT, but would need your proof of residence plus an overseas address for delivery outside the UK for us to process this for you.

How is my jewellery presented and is the packaging discreet?

We understand that our customers don’t want their precious jewellery arriving in branded packaging, opening them up to theft, or ruining a surprise.  Therefore we send all of our Ethica Diamond jewellery in a smart sturdy outer box, about the size of a child’s shoe box, that isn’t obviously jewellery.

Within that, your order is carefully wrapped in our beautiful signature packaging, ready to use as a gift. Whether it’s a solitaire engagement ring or a diamond pendant for someone’s birthday, we’ll make sure your fine jewellery is presented as attractively as possible.

For your convenience, your order details, as well as certification for the items you have purchased, are shipped at the same time, in the same package.

Help – I’ve made a mistake on my order!

Don’t worry, we will very happily help you with this. contact us and we will see what we can do.

If we’ve already dispatched your order, refer to our Return or Exchange Policy.

Do you ship internationally?

Yes. We will happily ship to anywhere in the world.

Please refer to our Packaging & Delivery details for further information.

Can I send my order to an alternate address?

For standard payment terms, yes, please complete your order via our website using your card’s billing address and your chosen delivery address, if they differ.

If the delivery address has changed since the order was placed, just contact us to let us know the correct delivery address.  We will update our system and send you confirmation of the revised delivery address.

However, if you have paid using our Interest Free Credit arrangements, to protect you against money laundering and fraud, we have to send your purchase to your registered address.  This is part of the terms laid out by our credit provider, and we are unable to change this.

Will I have to pay for international taxes and duties?

Ethica cannot control these costs and is not responsible for any duties/taxes applied to your package, so you will be responsible for paying additional charges if they apply.

In rare cases you might be contacted by customs to submit an invoice. In this case, you can simply forward our order confirmation email which you’ve received when placing your order.

If you should decide to decline a package you will be refunded minus a fee for returning the item to us and restocking it.

For international shipments outside of the UK, VAT is not collected at checkout. Ethica is not responsible for VAT and customs fees which will be charged to the customer directly by the shipping service provider.

Return & Exchange

What happens if the ring size is wrong?

We understand that it isn’t always possible to get the size right on the first attempt – surprise engagement rings are notoriously tricky!  We offer complimentary resizing on all of our engagement rings (excludes wedding bands) within the first 30 days. We also offer a resizing service for a standard cost of £125.00 which includes insured postage from our workshop and back to you.

All resizing work will need to be returned to us, to keep your guarantee validated.  Simply return it to us, insured with the postage, we will resize it for you and return it. 

Please see our Resize, Repair & Maintain guide for details. 

How do I return an order?

If for some reason you need to return an order, simply contact us to inform us that you wish to do so.  Provided the order is returned to us within 14 days, in its new condition with original packaging, we will happily process a refund. Please note that any costs you incur to return shipping is non refundable and a £40 fee will be deducted from your refund (if free postage was given at the time of purchase).

*This excludes bespoke, personalised/ engraved items, all wedding bands and re-sized rings. We will accept earrings back for an exchange equal to or greater than the original order value.

Bespoke Jewellery

I am not sure if I need to customise my ring. Where do I start?  

We offer relaxed and friendly, no obligation design consultations either face to face in our showroom or virtually in the comfort of your own home. So if you are not sure if what you have in mind needs to be necessarily custom made, our Concierge Specialist can guide you through the various options to help you to achieve your unique piece of jewellery.

What should I have ready for my no obligation design consultation?

Before your design consultation it would be great if you could have a few things ready. Firstly, you’ve probably taken a look at other rings and have already seen some that you like. It would be helpful if you could share any information on styles/designs with us so we can discuss the elements that you like.

Other considerations include metal type, finger size, carat weight or stone size, preferred stone shape and budget. Our Concierge Specialist will guide you through all of these questions during your appointment and then decide if we need to fully customise or semi customise your commission.

What happens after my design consultation?

Following your design consultation, you can expect to receive:

– Detailed quotes with various options via email.

– A choice of available gemstones from our trusted suppliers with 3D video and grading certification links for your consideration.

I want to involve my partner in the design process. Can they join us on our call?

Some partners like to propose to their better half with a promise ring and involve them in the design of the engagement ring. It’s a privilege for us, working with couples and an experience you can share together. We’re all in for you creating it as a duo!

Is there a minimum budget?

Our custom designed rings typically start at around £2500.

How long does it take to create my own ring? 

Production itself takes an estimated 21 business days. But the majority of the custom made process comes before, and it is dependent on how certain you are about what you want and the complexity of the design. Most designs take 2-5 days to complete with our Concierge Specialist, by a few emails and/or phone calls. Once you’ve approved your final design, our skilled team will start the process of bringing your ring to life. This typically takes around eight weeks, but may be longer depending on your design. You’ll be kept updated of your ring’s expected completion date and its progress throughout each stage. 

Do I pay upfront for my bespoke design? 

Creating your custom piece with Ethica Diamonds requires just a small deposit of £300 to get started. This fee is non-refundable but is applied toward your final order total. You can pay either directly by visiting our Jewellery Services or directly with us by bacs transfer. This fee is offset from your personal quotation. 

50% of the balance will become payable before your ring goes into production and the remaining balance before dispatch. Our preferred method of payment is by bacs transfer for customised jewellery. 

What happens after I have paid my deposit? 

Once the bespoke deposit is paid, our design team will begin work on your commission. You will receive 3D CAD images of your design concept approximately 4 days after your order is confirmed.

Can I see a model of my ring before it is made?

Most of the custom rings we create are produced using CAD, the best tool we use to create high-quality, custom pieces. The advantages of CAD are that you see an accurate virtual model of the jewellery prior to authorising its fabrication. You also have the opportunity to request design changes.

A wax model of the design can be made ahead of production and posted to you for £145. 

The cost of the wax is an additional fee which is a manufacturing set up cost for machinery downtime to produce the model. 

Some customers opt out of this stage due to tight timescales and the extra cost to build the model. Although it's not necessary, it does help some people visualise their piece more clearly and feel more confident about the overall proportions and fit. 

Can I make changes to my CAD before you produce my ring? 

Yes, you'll have the opportunity to make adjustments to your CAD design. Any major design changes are subject to additional fees and assessed on a case-by-case basis. However, these costs will be presented for approval prior to proceeding. Please note that additional design fees are non-refundable.

Will I get a 3D video of my ring design?

You will have the option to upgrade your render pack to receive additional CAD illustrations and a 3D video at an additional cost of £170. 

Can I have different stone types in my custom ring? 

We have a stunning selection of coloured lab grown gemstones (also called lab created gemstones or synthetic gemstones) that are the best on the market. They are created using the most scientifically advanced processes to produce beautiful, precision-cut, gemstones in a wide variety of colours, sizes and shapes, so you can add some colour and personalise your bespoke jewellery. 

See our Coloured Gemstones page for details. 

Can I use my own metal and/or gemstones for my custom ring? 

At Ethica, we are only able to work with gemstones and diamonds we have sourced ourselves, and precious metal that we know is not only recycled, but up to the quality standards that we must adhere to. We are unable to rework existing jewellery, or set gemstones that we have not sourced ourselves.

Can I get a custom design quickly? 

This is dependent on the design and specifications. When you design your own ring, please let us know your delivery deadline in your request form and we will confirm if it is possible.

Do you only make bespoke rings or can I customise other jewellery?  

Our Concierge Specialist can collaborate with you to custom design any type of fine jewellery including, but not limited to, engagement rings, wedding bands, everyday rings, necklaces, bracelets and earrings.

How much more does it cost to create your own ring compared to using an existing design? 

A custom ring does not necessarily cost more than a standard ring. You can work one-on-one with our Concierge Specialist to create a design that fits within your budget.

Do you offer finance on bespoke designs?

Yes. Helping to spread the cost of your bespoke jewellery could not be easier and the whole process can be done online in under two minutes. We  offer 0% interest free finance for 3, 6, 9 and 12 months on all orders from £250 to £15,000 with a deposit of between 10% –  50% of the value of the goods. Please note that deposits taken by our financial lending partner are separate to deposits that we may request directly with you if we need to secure a lab grown diamond or coloured gemstone for your commission.

See our Jewellery Finance page for details. 

Can I cancel my custom order after it has been placed? 

Once the rendering has been approved and you have paid for your custom ring, we are not able to cancel the order.

Can I return or exchange my bespoke ring?

Custom-designed jewellery is final sale and not eligible for return or exchange. We will work with you to ensure that you are completely delighted with the final product when you design your own ring.
